Abstract: A bridge plug arrangement includes a plug having an upper end and a bottom end. The bridge plug arrangement also optionally includes a cylindrical seat. The bridge plug arrangement further includes a tubular member. The tubular member may be part of a casing string. The tubular member is configured to receive the plug and, when used, the seat. The plug and/or the seat may be fabricated from a frangible material. Also disclosed is a method for diverting fluids in a wellbore using the bridge plug arrangement. The method may include landing the plug onto the seat within the wellbore below a subsurface zone of interest. Treatment fluids are then injected into the wellbore, where they are diverted through perforations and into a formation. The plug and/or seat is then optionally broken into a plurality of pieces through use of a downward mechanical force.

Abstract: A telebending tool for conveying a logging tool into a wellbore includes a tool body having a central axis. In addition, the tool also includes a cam housing coupled to the tool body and a nose moveably coupled to the tool body through a pivoting member. Further, the telebending tool includes a compression spring positioned between the nose and the pivoting member, and a camming arm coupled to the nose. The camming arm extends coaxially through the pivoting member to selectively engage a cam pathway of the cam housing. The nose has a first position with a central axis of the nose coaxially aligned with the central axis of the body and a second position with the central axis of the nose oriented at an angle less than 180° relative to the central axis of the body.
